An Asheville firefighter has been arrested and charged with shooting at a man on a bicycle.

Investigators said the gunfire erupted on Tunnel Road in Asheville when a man was riding his bike with his wife and 3-year-old son.

They say a man approached the father, upset that he was riding with his child in a bicycle seat in a high traffic area.

Authorities said Charles Alexander Diez, 42, got into an argument with the other man and that Diez pulled out a handgun and shot the victim.

They said the bullet struck the man’s helmet, passing through the lining, but stopping short of hitting him in the head. Authorities have charged Diez with attempted first degree murder.

Interim Fire Chief Scott Burnette with the Asheville fire department says that Diez was an engineer with the department. He was hired in 1992. The last change in his employment was when he was promoted from a firefighter to engineer in September 1999.
